Page 43: Common Equipment Description
• Overview The Cisco MGX 8220 is a 19-inch rack-mountable shelf. This shelf provides 16 slots for holding the modules (card sets) that provide the functionality. Each slot is designed to house two cards, a front card and a back card. Cards are installed in a slot as a two card set. A backplane runs across all 16 slots to provide signal connections between front and back cards, and between slots.
Page 44: Cisco Mgx 8220 Shelf
The shelf can house redundant power entry modules, which are small cards installed horizontally in the bottom rear of the shelf. The Cisco MGX 8220 shelf is powered by –48V DC power sources (single or redundant pair). Each power entry module is equipped with a circuit breaker. The shelf also provides a power receptacle for a cable to the cooling assembly, which is mounted in the rack below the Cisco MGX 8220 shelf (or shelves).
Page 45: Cisco Mgx 8220 Shelf
Cisco MGX 8220 Backplane The Cisco MGX 8220 backplane contains a main system bus, and the cell bus for communication between card slots. The cell bus consists of two pairs of unidirectional buses (for redundancy), which are used for transferring cells between the cell bus slave modules (FRSM, AUSM, ASC) and the cell bus master (BNM).
Page 46: Typical Cisco Mgx 8220 Hardware Weights
Power Entry Options DC Powered Systems In DC-powered systems, Cisco MGX 8220 supports one or two power entry modules (PEMs) each of which can be connected to its own independent 48V DC supply. The PEMs are installed horizontally, side by side in the bottom rear of the shelf. (See Figure 2-3.) Each module is powered from a 48V DC power source using three wires.
Page 47: Ac Powered Systems
875W of 48V DC power. The power assembly can provide power for up to four Cisco MGX 8220 shelves, requiring three power supply modules, or four for a (1 for N) redundant power supply configuration. The rear panel has four connectors which supply 48V DC power to the shelves.
Page 48: Dc Power Drain And Circuit Protection
The main cooling unit houses the fans that circulate air through the shelf. This unit is mounted below the shelves. This unit is capable of cooling up to two Cisco MGX 8220 shelves in the same rack. Racks that contain more than two shelves require a booster unit to provide additional cooling. The cooling assembly is powered from the main shelf.
Page 49: Main Cooling Assembly
(AC version only) Main Cooling Assembly The main cooling assembly provides cooling for up to two Cisco MGX 8220 shelves and is mounted in the rack below the shelf (or shelves). The cooling assembly consists of fans that draw air through the front grill and up through the shelf.

8-port T1 service modules. Rather than individually cable each of the 40 or 80 incoming T1/E1 lines to an MGX 8220 edge concentrator, the MGX 8220 backplane is designed with a distribution bus that allows an AX-SRM-3T3 to distribute T1s received “in bulk” to T1-based service modules. This eliminates the need for T1 back cards for each service module and the associated cabling and potential overloading of the digital cross-connect system port.

Other countries—International Electrotechnical Commission (IEC) 364 Parts 1 through 7 • The MGX 8220 shelf operates safely when it is used in accordance with its marked electrical ratings and product usage instructions. The following guidelines will help to ensure your safety and protect the equipment. The list of guidelines might not address all potentially hazardous situations in your working environment, so be alert and exercise good judgment at all times.
Page 156: Maintaining Safety With Electricity
The two 48V DC power feeds must be properly grounded on the positive 48V and safety ground pins. Ensure that the MGX 8220 frame and all other frames are attached to an isolated ground connection. For AC systems, an insulated grounding conductor that is identical in size to the grounded and ungrounded branch circuit supply conductors, but is green with yellow stripes, and installed as part of the branch circuit that supplies the unit.
Page 157: Site Preparation
The MGX 8220 shelf can be configured for either AC or DC power. An easily accessible AC or DC power source must be available within six feet of the MGX 8220 system. Before powering up the node, verify that the MGX 8220 node is powered from a dedicated branch circuit.
Page 158: Cooling
If you are going to mount the MGX 8220 switch in a frame or a cabinet that has front or rear doors, contact Cisco TAC to determine if the doors can provide adequate ventilation to the system.
Page 159: Unpacking Each Container
The unit must not be operated with any unused slots left uncovered. An inventory of the installed cards is taped to the MGX 8220 shelf showing the serial number, the Note revision number, and the slot number for each card.
Page 160: Horizontal Positioning
MGX 8220 modules are designed to be mounted to two vertical rack-mounting rails. A front-mounting rail is used as one mounting point using the flanges provided at the front of each MGX 8220 module. A second rail, either at the rear of the rack or at an intermediate position, is used for the second mounting point (mounting brackets are provided for attaching the module to the second rail).
Page 161: Cooling Configuration Guidelines
Cooling Configuration Guidelines To ensure that the MGX 8220 switch gets proper ventilation and is cooled properly, you must adhere to the following cooling configuration guidelines: You must never have more than four (4) shelves installed between the air inlet and the air exhaust.

Connect two T3 coaxial cables between the T3 BNC connectors on the MGX 8220 BNM line module card and the T3 BNC connectors on the BPX BNI line module. The transmit port on the BPX line module and the receive port on the MGX 8220 BNM line module must connect to each other. (See Figure 7-22.)
Page 183: Making The Service Interface Connections
T3 trunk Making the Service Interface Connections The customer data is connected to the MGX 8220 shelf through T1, E1, X.21, or HHSI lines. Service lines using DB15 and RJ-48 connectors need only one cable per port. Service lines using BNC or SMB connectors require two cables (one transmit and one receive) from the E1 port of the customer equipment to on E1 port on an MGX 8220 line module.
Page 184: Alarm Output Connection
Making External Clock Connections If the MGX 8220 node is to be synchronized to some other external equipment or a local digital central office, a connector on the back card can be used to provide a clock input.
Page 185: Initial Start-Up Of The Mgx 8220 Shelf
“MGX 8220 Service Modules,” provides details of this command. Initial Configuration Before the MGX 8220 shelf can receive commands, SNMP requests, file downloads, and so on, the shelf must be assigned IP addresses for the control port, the LAN port, and the in-band channel. This procedure requires a alpha-numeric terminal to be connected to the maintenance port of the active ASC card and addresses assigned through the command line interface.
Page 186 Chapter Initial Start-Up of the MGX 8220 Shelf Step 4 While you are using the terminal, you can assign a nodename for the shelf entering the cnfname command. If you type any command mnemonic and press Return, the screen displays the syntax for Note that command.
Page 187: Chapter 8 Repair And Replacement
Preventive Maintenance Most monitoring and maintenance of the MGX 8220 shelf is done using the operating system software. Preventive maintenance of the MGX 8220 shelf hardware is minimal. Periodically check the node supply voltage and internal cabinet temperature. The temperature should not exceed 50 C.
Page 188: General Troubleshooting Procedures
General Troubleshooting Procedures The MGX 8220 shelf run self-tests continuously to ensure proper function. When the unit finds an error condition that affects its operation, it downs the card or line that is affected. If it is caused by a card failure and there is a redundant card, the failed card is downed and the standby card becomes the active card.
